LME49720: Excess / Popcorn Noise Issue

Part Number: LME49720
Other Parts Discussed in Thread: LM4562,

Hello TI,

I was about to choose an LM4562 / LME49720 for an audio amplifier application as their price vs performance on the face of it looks fantastic.

I have been somewhat alarmed however that in April 2015, Sept 2018 and Jan 2019, there are reports of high levels popcorn noise coming from a very high percentage of units. This noise totally ruins the noise characteristics of the chip, and I suspect the end application they are going in if the constraints are strict.

Has this issue been addressed during manufacture, or has extra post-manufacture testing been instigated since Jan 2019? Or are they still being created and tested in the same way with no change?

Thanks for the help,
